The United States said on Wednesday that it had secretly removed malware from computer networks around the world in recent weeks, a step to pre-empt Russian cyberattacks and send a message to President Vladimir V. Putin of Russia.
The move, made public by Attorney General Merrick B. Garland, comes as U.S. officials warn that Russia could try to strike American critical infrastructure — including financial firms, pipelines and the electric grid — in response to the crushing sanctions that the United States has imposed on Moscow over the war in Ukraine.
The malware enabled the Russians to create “botnets” — networks of private computers that are infected with malicious software and controlled by the G.R.U., the intelligence arm of the Russian military. But it is unclear what the malware was intended to do, since it could be used for everything from surveillance to destructive attacks.
